Hello my friends.
By now some of you will have gotten your new tappers. For that I thank you. It's been a real struggle to keep things running I can tell you that. After being a mechanic and machinist most of my life, it always amazed me, and still does - how something could just up and break - but it does. I've been nursiing the old Harbor Fright bandsaw for weeks now, trying to keep a motor on it running, and jury-rigging ANYTHING up to it to keep that saw blade running. Without it, I am dead.
My last and final attempt to prolong the life of the old girl was to hook up an old Baldor 3/4hp DC motor and driver to it. That did work for a little while, but read on...
In my old job, I changed many a motor and controller. I'd sometimes change both the motor and controller and save the old components. Many times the old motor just needed some cleaning and replace the brushes. Instead of trashing them, I took them home. Wouldn't you think I would have a motor to fit that old saw? No way could I find anything that would at least sort of work. I've had four motors on it and they all have either burnt out from over work, or old age. This dc motor was no exception. It sparked and zapped and blasted a shot of smoke and sparks out of the wire-hole that leads into the windings. I took it apart, and the lead wires had frayed and caused a short. So much for that.
Well the final straw have arrived and as much as I loathe the idea, I must buy another HF saw. I'll order one today. I guess it'll take me a couple hours to tweek it up, and mount it on the good base I made for the old one. I'll also need to run the coolant lines on it.
The good news is that I'm still happily self-employed!
